(SPRINGFIELD, Mo.) — The FBI announced a $25,000 reward on Monday for the recovery of screenprints of Andy Warhol’s iconic Campbell’s soup can that were stolen from the Springfield Art Museum in Missouri.

According to Springfield police, the break-in happened sometime last week between Wednesday evening and early Thursday morning. The art was stolen from the museum’s exhibit titled, “The Electric Garden of our Minds: British/American Pop,” which has remained closed since the theft.

According to the FBI, seven of the 10 prints were stolen. The collection, owned by the museum since 1985 and created by Warhol in 1968, is worth about $500,000.

Springfield Art Museum Director Nick Nelson said in a statement that the museum was working with the authorities to ensure the proper security was in place while the museum remained open to the public.

Local artist Pam RuBert, who has some of her work displayed at the museum, said it was scary someone would steal the art but, called it a “validation of the value of art.”

“I can’t believe that would happen,” she said. “I mean, you think of Springfield as the kind of place that this doesn’t happen in. I guess it shows the value of art and that this can happen anywhere.”
